    Question Need Help Simplifying an Equation...

    Can someone please help me in simplifying the following:

    y= -2(x/2)^2 - 15(x/2) - 22

    I'm having problems with an assignment question because I can't remember how to do this one step... its been awhile since I took math.

    Thanks.

    From y=-2(\frac{x}{2})^2 - 15(\frac{x}{2})-22, perform the squaring and rewrite as

    y=-\frac{2x^2}{4}-\frac{15x}{2}-22, express in common denominator as

    y=\frac{-x^2-15x-44}{2} and clean up the signs to get

    y=-\frac{1}{2}(x^2+15x+44)

    y = -\frac{1}{2}(x+4)(x+11)
